. To all whom it may concern:

Be it known that I, illonamso on BENE- DIC'IIS, citizen of the United States, residing in the city and county oi San Francisco and State of California, have invented new and useful Improvements :in Fumc-Comlensers, of which the following is a specification.

This invention relates to smoke and fume condensers.

It is the object of this invention to provide av condenser for separating the volatile substances, dust particles and the like, from smoke and fumes, which is simple in construction and ellicient in operation, and which is ntrticularly adapted to handling smoke and fumes in a large volume, thus providing a condenser which is applicable for use in large smelting and manufacturing plants.

A further object is to provide a smoke and fume condenser which is so constructed as to be readily accessible for cleaning, rcpll"ll'lg and for the removal of the materials collected and separated from the fumes.

The invention consists of the parts and combination and construction of parts hereinailter more "fully described and claimed, having reterencc to the accompanying drawings, in which- Figure l is a perspective view of the in venlion with parts broken away. Fig. 2 is a plan view partly in section. Fig.3 is a detail of the suspended ballle bars. Fig. 4t is a detail of the beater drum.

in the drawings A represents a smoke room or chamber, preferably constructed ol reinforced concrete or other masonry, and which is shown as cubical in form and inclosed on all sides. A partition i so disposed in the chamber A as to convert the interior of the latter into a continuous winding narrow compartment, one end of which is open to a tlue 3, leading from a furnace or furnaces of any description, and the other terminating in a smoke stack or chimney 4 rising to any suitable height from the roof of the chamber A. A series of perforated pi pcs 5 are disposed at suitable. intervals across the ceiling and down the side walls of the Winding compartment or smoke chamber, and are preferably constructed of tile, ghss or other vitreous material, not subject to the action of chemicals contained in the fumes or the water which they are designed to carry. These pipes 5 are so perforated that they will discharge a series of fine jets of water throughout their length; the horizontal pipe extending across the ceiling of the smoke chamber discharging in a downward direction while the vertical pipes discharge in a horizontal direction parallel with the ceiling pipe connected therewith, so as to form virtually a line not work or wall of rapidly moving water complctely across the smoke passage in the chamber A, at suitable intervals.

Ballle bars (5, suspended in rows in stag gcrcd arraugcimuit, are disposed across the smoke passage between the thin sheets or walls of water, as indicated in Fig. 2; these ballle bars being constructed of any suitable material and suspended from hooks on a glass rod 7 disposed near the ceiling of the smoke passage. These batlle bars are of such length as to extend from the ceiling to the floor of the smoke passage and are arranged in rows slightly separated from each other entirely across the passage.

Revoluble drums or cylinders, 8 8 formed of a series of horizontally disposed slats, are placed adjacent the intake and the discharge openings at each end of the smoke passage and are a daptcd to be rotated in any suitable manner, so as to create an artificial draft or suction in the smoke chamber; the slotted drum 8 at the intake breaking up or ditlusing the smoke volume as it leaves the flue 3.

A pair of discharge openiugr 1 are located in one end of the chamber 1 at. a point adjacent the floor thercol for the purpose of carrying away the water delivered by the spraying pipes 5; these openings 9 being provided with gates or doors 10 for closures, and are separated from each other so as to discharge at different points into separate ditches or troughs 11 which may be open to the atmosphere, the bottom or floors of which are a 'iproximately level and situated below the plane of the floor of the smoke cluunber A. These troughs are,prel.- crably formed of masonry and terminate in wells or settling tanks '12 on each side of the smoke chamber A. The water flowing into the tanks 12 is removed by pumps 13 of any suitable description, which discharges the water into a reservoir 14 disposed above the smoke chamber A; an overflow pipe 15 lead-f ing from near the top of the reservoir 14: back to the tanks 12. i

Th spraying pipes 5 are connected to the rece' voir 14 through a pipe 16 leading from "he bottom of the latter, thus providing means by which the water may be used again as many times as desired.

In operation, the smoke or fumes to be treated are delivered to the smoke chamber A from the flue 3 whereupon they are driven forward by the slotteddrum 8 through the thin sheets or walls of water formed by the pipes 5, and througl? the suspended baflle bars 6, the water acting to cool the fumes and precipitate certain particles therein, and the bafiie bars 6, collecting on their surfacessiich particles as arenot removed by the water. The passage of the' currents of fumes and gases passing between the battle bars swing them on their pivotal mounting to cause them to strike one another and 7 tremble, so as to continually loosen the particles collected thereon and causing them to fall into the water on the floor of the smoke chamber. The particles collected by the water are carried off through either of the discharge openings 9 into the troughs .11 and settling tanks 12; the heavier particles settling to the bottom thereof. A double arrangement of the troughs ll'and tanks 12 is provided so that while one is in use the other may be cleaned, thus permitting of a contil'luous operation. The Water delivered to the tanks l2 is pumped to the reservoir 14 to be used again, as before described. The water after being used some time becomes acidified whereupon it is subjected to further treatment or is employed in any manrer desired.

cut is \Vhen the water is drained from the troughs l1 and tanks 12, the sediment collected therein is removed to drying bins l'idisposcd adjacent thereto.

By subjecting the fumes-and gases to the treatmcntjust described, they become thor oughl y cleansed of dust and poisonous par ticles, so that when discharged from the stack 4; they are entirely free from mineral substances.

Having thus described my invention, what- I claim and desire to secure by Letters Pat 1. A fume condensing apparatus consisting of a chamber adapted to receive the fumes, partitions forming Vertical tortuous passages, perforated Water spraying pipers located within the sides and top of the pas sagcs and adapt d to discharge both trans- Vcrscly and downwardly through the pass-i 1 ing tuu'ies, and battle bars suspended between the spray pipes and arranged in the path of and crosswise of the sprays delivered by the side pipes.

2. A fume condensing apparatus comprising a chamber, means for transmitting fumes therethrough, partitions forming vertical tortuous passages, perforated Water spraying pipes located within the sides and top of the passages and adapted to discharge CIGiiS-St1eflIL1S transversely and downwardly through the passing fumes, and baflle bars suspended between .the spray pipes and arranged in the path and crosswise of the streams delivered 'by the side pipes, said bars being capable of an agitating movement.

3. The combination in a fume condensing apparatus, of a series of narrow tortuous passages, means for transmitting fumes therethrough, means for discharging crossstreams of fine sprays of water through the assing fumes, and suspended swinging bafie bars disposed within' the chambers and between the spraying means and across the line of flow of thefumes.

r 4. The combination in a fume condensing apparatus, of narrow vertically disposed tortuous passages, means for transmitting fumes thcrethrough, means for discharging cross-streams of fine sprays of Water transversely and downwardly within the passages, independently swinging bafilebars located bet-ween thespraying means and across the line of flow of the fumes, and revoluble slatted drums located within the chambers and adapted to create a draft and' to break up the volume of fumes.

5. The combination in a fume condensing apparatus, of narrow vertically disposed tortuous passages, means for transmitting fumes therethrough, means for discharging
